March – Gunsmoke is renewed by CBS for the fall 1967 season. Aging (it was completing its 12th season) and declining in the ratings, CBS planned to cancel the western, but protests from viewers and even members of Congress lead the network to move the series from its longtime late Saturday time slot to early Mondays for the fall—displacing Gilligan's Island, which initially had been renewed for the fall but is canceled instead. Gunsmoke would remain on CBS until 1975.
